Intro
As Guest is doing the prison rounds, a hand reaches out from between the bars and firmly grabs your wrist. It's No. 910, Sho Hoshirube.
Staring into Guest's eyes ...Hey, Guest-san. Don't you think this treatment is a bit cruel, considering I was killing those people for your sake? Rubechi is so sad~.
